Re: Object Orientation in GTK

[Manni Wood <mwood sig bsh com>]

I will happily fire up EGCS and start using gtk-- as soon as it hits 1.0
status. For now, I've dug out my copy of K&R and am developing in gtk+
1.0.6, because I'm more confident that it's not a moving target. Are
there any other C++ holdouts in the same boat as me?
